THREAD-GUIDE FOR SPINNING-FRAIVI ES.

' specification.

The object of this invention is to produce a thread-guide so constructedthat when it becomes necessary to piece up an end of the yarn on thebobbin as soon as the fingerboard is swung forward the yarn Which isbeing revolved by the bobbin is caught by the thread-guide and conductedto the eye, thus doing away with the slow process of inserting thethread in the eye by hand.

The nature of the invention is fully described below and illustrated inthe accompanying drawings, in which- Figure 1 is a plan viewillustrating my improved thread-guide (two being shown) in position inthe edge of the finger-board. Fig. 2 is a sectional end elevation of thesame. Fig. 3 is a front elevation. In Figs. 1 and 3 the thread or yarnis shown in dotted lines entering the slot in the thread-guide and infull lines in position in the eye.

Similar letters of reference indicate corresponding parts.

a represents an ordinary finger-board or guide.

My improved thread-guide comprises an integral plate of sheet metal orother suitablyprepared metal or material, one portion Z) of which issubstantially horizontal and the other portion 0 of which is nearlyvertical, being at a slightly-obtuse angle with the portion 6, saidportion Z) constituting the tailpiece and being provided with akink-catcher d, not new in this invention. Integral or rigid with theportion I) is a screw 6, by means of which the thread-guide is securedto the outer edge of the finger-board in the ordinary manner. Theportion 6 of the plate is provided with a long horizontal arm f,extending from the opposite side from the tailpiece and nearly parallelwith the front edge of the finger-board. The outer edge f of this arm ispreferably slightly convex. A short arm g extends from the main portionof the plate (Z and curves slightly outward, as shown, its rear edge andthe front edge of the shank portion of the arm f being of such a shapeas to produce a narrow slot or passage 7, having a flaring mouth it.This passage leads at its inner end to a comparatively large hole a inthe portion 6 of the plate, all as illustrated in Fig. 1.

In operation after the finger-board has been swung back, the bobbinplaced on the spindle, and the finger-board swung forward the end of theyarn on the bobbin which is held in the hand is caught by therevolutions of the bobbin by the thread-guide and is guided by the arm fand the outer end of the arm g into the flaring mouth/r of the slot orpassage 72 and thence into the eye 12. The end of the yarn which is onthe bobbin may then be pieced to the end coming out of the rolls. Bythis means in piecing up an end the yarn is conducted into a thread-eyeby the revolution of the bobbin instead of being inserted therein byhand, and much time thus saved. When the finger-board is thrown back todot? the bobbin, the thread is doubled over and the doubled-over portionheld against the outer edge of the arm g nearly opposite the eye 02 bymeans of the concave curvature of the outeredge of said arm and retainedin said position until the board is lowered.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

The herein described improved threadguide for spinning-frames,comprising a horizontal plate 6 provided with a horizontal arm f adaptedto extend substantially parallel with the outer edge of thefinger-board; and the arm g extending from the portion bin the directionof the arm f and for a considerable distance along its outer edge, theouter edge of said arm g being slightly concave whereby its end or pointprojects slightly outward, and the inner adjacent edges of the arms 9and f being respectively convex and concave whereby a passage ofsubstantially even width for the most of its length is produced, themain portion being provided with the eye n connecting with the inner endof said passage, whereby the revolution of the bobbin automaticallyconducts the thread into the threadeye, and when the finger-board isthrown back to doff the bobbin the thread is doubled over and heldagainst the slightly-concave edge of the arm g, substantially asdescribed.

In testimony whereof Ihave signed my name to this specification in thepresence of two subscribing witnesses.
